God has entrusted Sion with a special gift or charism - "to witness in the Church and in the world that God continues to be faithful to the Jewish people". (Constitution no.2)
We are called to witness by our life to God's faithful love for the Jewish people. Our call implies that our apostolic life is characterised by a three fold commitment:
to the Church,
to the Jewish people, and
to a world of justice, peace and love.
Whatever task we are engaged in, we are called to integrate in some way these three dimensions of our apostolic commitment (From our constitutions)
